摘要

摘要: 通过大量样品的封闭体系热压模拟实验,对比研究了不同性质、不同组成海相古油藏及可溶有机质热裂解再生烃(气)能力及其产率分布特征。结果表明,不同海相古油藏与可溶有机质的再生烃气能力大小为:凝析油>轻质油>正常原油>志留系沥青砂岩≥稠油≥低成熟固体沥青≥含沥青灰岩>稠油油砂>氧化固体沥青;其再生烃气能力除与岩性、赋存状态、演化程度等有关外,主要受所含可溶有机质性质和组成的制约;可溶有机质再生烃过程是干酪根生烃的延续,其生烃气潜力与干酪根烃源岩相当,当其达到高过成熟阶段时,可以作为新的轻质油气或者天然气来源。

Abstract: Based on the results of thermal simulation of many samples at conditions of close system,the hydrocarbon-regeneration capabilities and yield distribution features of soluble organic matter and marine paleo-reservoir which has different properties and different compositions(extra heavy oil,normal crude oil and light oil) were studied.The results indicate that the hydrocarbon-regeneration capability of different marine paleo-reservoir and soluble organic matter were ranked in order of condensate oil light oilnormal crude oilSilurian asphaltic sandstones≥heavy oil limestone≥low-mature solid bitumen≥asphalt-bearing limestoneheavy oil sandoxidation solid asphalt.This capability was mainly controlled by the properties and compositions of soluble organic matter besides factors of lithology,occurrence state and evolution degree.Hydrocarbon-regeneration process of soluble organic matter was continuation of hydrocarbon generation from kerogens.The hydrocarbon generation potential of soluble matter was equivalent with that of kerogens.They could be used as light oil or natural gas source when their temperature arrived at over-high mature stages.
